Definitions

  • the object of the invention is a valve for the maintenance of sterile conditions in a filler machine.
  • repair work to the headers which requires the opening up of the said headers causes loss of sterile conditions not only in the headers themselves but also in the components connected to them, such as for example the filler valve and the product feeder conduit.
  • An aim of the present invention is that of eliminating the above-described drawbacks and in particular to realise a device for separating the product feeder conduit from the header while maintaining sterile conditions in the said conduit and in all the apparatus connected to it, and thus avoiding the need to re-sterilise in the case of maintenance operations which regard the headers and the filler valves.
  • valve for the maintenance of sterile conditions object of the present invention, for filler machines in sterile environments, of the type having one or more headers equipped with filler valves, in which headers a branch of a product feeder conduit is inserted, characterised by the fact that the said valve, associated to each header, comprises means aimed at interrupting the product feeding to the filler valve which is out of order and thus at preserving sterile conditions in the product feeder conduit, which means are characterised by:
  • 1 denotes a product feeder conduit, destined to feed one or more headers of known type, indicated by 18 in figure 3, equipped with filler valves 19 through which containers 20 are filled.
  • a plurality of branches 12 of the conduit 1 place the conduit 1 and the headers 18 in communication.
  • the first plug 2 is solid to a piston 7 housed internally to a cylinder 6 and is vertically mobile.
  • the plug is kept in a closed position by means of a spring 5 which presses on the piston 7, while the opening of the plug 2 happens by means of the immission of air or other fluid through an aperture 8 bored into the cylinder 6 in such a way as to raise the piston 7, compressing the spring 5.
  • the cylinder 6 is equipped with a bleeder hole 15.
  • the spring 15 be positioned below the piston 7 and the aperture 8 above the piston, so that the spring 5 would be compressed in the case of the plug's 2 being closed.
  • the spring 5, the piston 7 and the cylinder 6 equipped with aperture 8 and bleed hole 15 constitute means for the activating of the first plug 2.
  • a chamber 27 is defined between the second plug 3 and the first plug 2, into which steam or other sterilising fluid is introduced.
  • the stem 3a is solid to a piston 9 which piston is slideable internally to a chamber 10 due to the variation of pressure which occurs in two separate spaces 10a and 10b of the said chamber 10 when air or other fluid is introduced by means of respective inlet conduits 11a and 11b.
  • piston travel limiters Internally to the chamber 10 there are two piston travel limiters, one lower 16 and one upper 17.
  • 21 and 22 denote respectively an inlet conduit and an outlet conduit for the sterilising steam or condensation or other sterisiling fluid.
  • the inlet conduit 21 and the outlet conduit 22 for the steam, with the cavities 4 and 24 constitute means for the immission of steam or other sterilising fluid into the chamber 27.
  • Said feedig means for the steam or other sterilising fluid are structured in such a way that there is not possibility of introduction of the product into the inlet and outlet conduits 21 and 22 for the sterilising fluid or steam, avoiding thus the possibility of blocking of the said conduits 21 and 22.
  • the first and second plugs 2 and 3, the stem 3a and the cavities 4 and 24, constitute means aimed at stopping the feeding of the product to the filler valve 19 and at preserving product feeder condu it 1 steril ity.
  • An advantage of the present invention is that when the headers 18 must be cleaned or maintenance on them must be performed, requiring that they be opened, this can be done without the consequent need to clean and sterilise the entire machine, it being necessary only to sterilise the branch 12 and the part of the machine comprised between the branch 12 and the filler valve 19 associated with it.
